To all whom,l tmay concern/- Be it known that-I, THoMAs.W.-MORGAN, a citizen vof the United States, residing at Waterloo, lin the county of Blackhawk and useful Improvements in Centrifugal Cream-' Separators, of which the following isa speci- My invention relatesito improvemer'its in centrifugal cream separators, andthe object able exitI for theescaping skimmed mi k so arranged as to permit of any desired change in the density of the se arated cream. This which are hereinafter described and claimed, and which lare illustrated in theiaccompanyigure 1.is a centralvertical axial section of the-conical cover of a 'centrifugal'crealn se arator bowl'provided with my improved a justable .milk exit screw and auxiliary means for permitting any desired changein the density of the esca ing separated cream, and Fig.- 2 is an upper plan view ofsuch cover, its upper cylindrical portion being shown-in horizontal section taken on a line :c in Fig. 1. Similar letters refer to similar parts throughout the several views.

.The conical cover a has .an upper cylindrical extensionfprovidedwith an inwardly, extending il e or fillet g, the inner periphery of' said cylindery f 'also having'an annular recess h in communication with `the space 1 between` said .cover and the inner cone "c. TheA removable hollow inner 'conev c is spaced apart from the inner eriphery of the cover a by means of a` lura ity of lu s b extending inward from sai cover. Said u s are short. enough so as to not interfere wit the equal dissemination of the stratum of `skimmed milkover the whole inner peripheral surface of the cover ai The upwariilhollow portion ofthe inner cone c is -in the form of a cylinder having a plurality .of inwardly directed threaded ope Ial-iiscrew may be made' to apinner end of s C -proach more or less closely to' the 4crimped-1n The stratum of escaping skimmed milk which passes over the inner periphery of the cover a is very shallow in depth, and when 'the screw 'i has been adjusted so that itsinner end lies llush with the inner surface Of the recess h the bowl will skimso as to leave the The o ject of crimping in the cylinder d to form the Offset portion eis tO permit the in-` v,ner end of the screw i to pass to-a position vWhere its inner 'face lies in the same vertical line as the innersurface of the cream conduit d. lThe offset eis suicient, as shown 4in Fig.

2, to permit of this last adjustment of the screw 'i and also leave a suflicient space between said screw and said offset e to permit ofy the free passage of milk therebetween. The

ca tical line as that of the inner surface of the adljustment of the screw 'i to bringI the verti-l surface of its inner end into the same ver-J cream conduit d is especially effective in that it allows the maximum adjustment for effecting a less density in the separated cream. The cone c, when the cover a has been re moved from the bowl, 4may be easily removed for cleaning.

Having described my invention, what I l claim as new, and desire to secure by Letters Patenth is-.-

1. In -a centrifugal cream separator, the combination with the removable cover containing a milk exit whose inner receiving end is adjustable toward and from the axis ofthe bowl,of an inner cone contained in and spaced away from the said cover 'and adapted to separate the issuing streams of separated milk and cream, the cylindrical top of said IOO cone being crimped inward at a point nearest the .receiving end of said adjustable exit-to permit said receiving end to lie in the same vertical line as the outer line of the cream stratum.

"2. In a centrifugal, cream separator, the l y 1o crimped inward at a point nearest the receivingr end of said adjustable exit to permit said receiving end to lie in the same vertical line as the outer line of the cream stratum.
